State agency greenhouse gas reporting

Washington is dedicated to reducing greenhouse gas emissions to help slow the impacts of climate change. State agencies are joining the effort. With direction from the Legislature, state agencies are working with us to monitor and reduce their emissions.

State Agency Climate Leadership Act

The State Agency Climate Leadership Act (RCW 70A.45) requires state agencies to reduce their greenhouse gas emissions. It applies to some state agencies in Washington, including colleges and universities. Agencies must reduce carbon pollution below 2005 levels:

  • 15% below 2005 baseline by 2020
  • 45% below 2005 by 2030
  • 75% below 2005 by 2040
  • 95% below 2005 by 2050,  achieve net zero

Reports to the Governor and the Legislature

The Legislature recognized the need to address the threat climate change poses to the state and, in 2008, established statewide limits on greenhouse gases. As part of the response to climate change, the Legislature required state agencies to reduce their greenhouse emissions (GHG) and report on their progress every two years.

Changes to the reporting program

Starting with the 2016 report, we updated the tools and requirements for state agency greenhouse gas reporting. There are new reporting thresholds, which means some agencies no longer need to report their emissions. Check the list to see if your agency is required to report. The reporting deadline is July 1, 2020.

Tools for reporting your emissions

Agencies should use the tools below for calculating and reporting:

Other required greenhouse gas reports

Some agencies emit larger amounts of greenhouse gases and have additional reporting requirements to EPA and us. Visit EPA's greenhouse gas program to determine if your agency is required to report under federal requirements and visit our facilities greenhouse gas reporting page to check for additional state reporting requirements.
